I posted fuel cell info on the pre 88 page. I’m going to try the 89 and up. I put an rci cell in my truck this is what I have so far. This is a 10 gallon cell with a Holley sniper in tank pump. Still in the working stages. But I’m able to start the truck. My question is the sending unit! I tested the wiring one is ground I think is green. Hard to tell. There’s two wires with stripes maybe white and black. It’s hard to tell. I believe one is for the low fuel light because it blinks when I tested it. If I hook the other white wire to my rci sending unit and ground it, the gauge doesn’t work. But if I touch the low fuel light wire to the sender hot,the gauge works. Is this the correct way? By the way it works backwards says how’s full on empty.
